Social media companies play an outsize role in global politics — from the US to Myanmar. And when they fail, their actions can cost lives.

That's why Frances Haugen blew the whistle against her then-employer, Facebook, when she felt the company hadn't done enough to stop an outrage-driven algorithm from spreading misinformation, hate, and even offline violence.

On GZERO World, Haugen tells Ian Bremmer why governments need to rethink how they regulate social media. A good example is the EU, whose new law mandating data transparency could have global ripple effects.
